Answer 2

What do you think is necessary to conduct heat well?

Answer 3

the best is silver

Answer 4

Air has no conducting properties.

Answer 5

The point that @Vincent-Lyon.Fr is getting at is that a regular structure is generally required to conduit heat well. Gases don't have a regular structure and are poor heat conductors. Glass doesn't have a regular structure, so it's not typically a good heat conductor. Metals have a nice regular crystalline structure with which to conduct atomic kinetic energy (temperature is the measure of the average kinetic energy of particles) and thus heat.

Answer 6

Yep! Since heat conduction is a microscopic transfer of molecular agitation, then the atoms or molecules have to be close to one another (in a dense medium) in order to transmit their energy effectively.
All gases are poor heat conductors.
